1 Claim.

The present invention relates to new and useful improvements in lathe tools, and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character comprising a novel construction and arrangement whereby a number of different operations may be expeditiously performed on a piece of material without the necessity of removing said material or the tool from the machine.

Other objects of the invention are to provide a lathe tool of. the aforementioned character which will be comparatively simple in construction, strong, durable, highly efiicient and reliable in use, compact, and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure l is a perspective view of a lathe tool constructed in accordance with the present invention.

Figure 2 is a perspective view of the tubular adjustable arm.

Figure 3 is a perspective view of the clamping rod.

Figure 4 is a perspective view of the bit or cutter.

Figure 5 is a detail view in perspective of the clamping nut.

Figure 6 is a view in vertical longitudinal section through the assembly.

Figure 7 is a cross-sectional view, taken substantially on the line 11 of Figure 6.

Figure 8 is a fragmentary view in horizontal section, taken substantially on the line 88 of Figure 6.

Figure 9 is an elevational view, looking at the forward end of the tubular arm.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a holder of suitable metal which is designated generally by reference numeral l The holder l includes a bar 2 for mounting in the usual post on the lathe. Projecting at right angles from one end portion of the bar 2 is an integral, split clamp 3. A bolt 4 closes the jaws 5 of the clamp 3.

A tubular metallic arm 6 is rotatably and slidably adjusted in the clamp 3. As illustrated to advantage in Figure 2 of the drawings, the tubular arm 6 has formed in its forward end portion diametrically opposite, aligned notches or recesses I. The notches 1 are for the reception of the substantially U-shaped portion 8 of a bit or cutter 9 which is mounted transversely on the forward end portion of the tubular arm 6.

A rod I0 i provided for clamping the bit 9 in position. Toward this end, the rod It! has formed in its forward end portion a diametrically extending opening I I in which the bit 9 is inserted prior to engaging said bit in the notches l.

The end portion 12 of the rod I0 is engageable in the substantially U-shaped portion 8 of the bit 9. The rod l 0 passes through the tubular arm 6 and terminates in a threaded rear end portion [3 which receives a clamping nut [4. The nut I4 is engageable with the rear end of the tubular arm 6 for tightening the rod ID on the bit 9.

It will thus be seen that a lathe tool has been provided which may be expeditiously adjusted to perform several different operations on a piece of work. Of course, the entire assembly is adjustable 0n the lathe in the usual manner. Then, by simply loosening the bolt 4, the tubular arm 6, with the bit or cutter 9 thereon, may be rotatably and slidably adjusted as desired on the holder I. The construction and arrangement is such that the bit 9 is secured on the tubular arm 6 in a very strong, rigid manner.

It is believed that the many advantages of a lathe tool constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

A lathe tool comprising a tubular arm, means for mounting said arm on a lathe post, said arm having aligned notches in one end portion, a rod mounted in the arm and having an opening therein, a bit including a substantially U-shaped central portion having its ends engaged in the notches of the arm and its intermediate portion engaged in the opening of the rod, and a nut threaded on the rod and engageable with the arm for tightening said rod on the bit with the portion of the rod at the outer side of said opening seated in the U-shaped portion of the bit.
